Hi All
I'm thinking about a new lighter summer / shoulder TQ.
Probably with 1.5" baffles and around 9-10oz of 900 fill. (Aiming for a 30°F rating)
At this stage I'm looking at using some Thru Hiker M50 for the outer shell and 7d or 8d for the inner shell from Titanium goat.
Is there any huge reason to pay more than double amount and use 7d over 8d ($20/LY vs $7.50/LY) for the inner shell.
